My inventionr'clates tol shuttlef'clieclring 1 L' arrestin within the shuttle b9xes iof i type or class wherei'r`1-'the'swel4 shuttlebox is madefuse o with the shuttle, as it enters s di "t0 brine about the gremial@ e vmotion in a more Vdesfed manner thanhe tofore, thereby securingbienei v c apparatus or to "shuttle of the use of looms.'

My present inventionconsists'in thehinployment of cam actatedfle'ver.devices so constructed andV arranged that they vmay be readilyfadjusted and'when" mounted in position will control the actiensoffthe swell'jlever sov that sameislbrought into use "atfthe exacttiine 'desired relative `to "the` .other actionsoiI the loom in 'order tocarrylout the gradual' retard'in'g and Varresting of thc1 1notions of the shuttle under thebest' possible conditions foi-:securing said arresting'of the shuttle without causing excessive'weary deterioration and'breakages. l

In order thatmyv said inventioirmay be readily understood I have hereunto appended sheets of drawings illustrative thereof to which by figures and letters re''eren'ce is made in Vthc followingdescription Fig. 1 is a sectional end 'elevation'of sufficient of the end frame of alecm', the slayboard, the laysword 'and the crank sha-ft .of said loo'm witlrother` parts Vin connection therewith to illustrate theV application of my improved devices.

""" I 1r ;ill"the drawings these part-s are shown `1"'onc` 3n dolg the loom only, but it is to erstoodjtjhat the sameparts arranged respective positions are employed Vl er" end of the same loom so that bmg the devices vat one end of the "lboni'i t` will readily be understood how their ons vmay be brought into use at both ends theyl o' )1ns. v. '.'The' crank shaft C is coupled in the usual ymannerl to the slayboard A by the arms or connecting rods c.

In carrying my invention into eiieet in @connection with the type of loom illustrated vby Figs 1,2 and 4 wherein the crank shaft is so situated, between the two end frames D of :thel loom, thatl a space exists between the sweep of lthe crank C and said end frame D' to enable the adjustabl 'position Vupon said crank shaft Cl; '.2 whichy is preferably of the shape shown. lby Figs. l 'and'lsy The l'cam 2 is arranged to actuate a lever whichy is pivoted at40 to theend frame D at the rear of the loom, while said lever 3 is so shaped that' it will extend over said cam 2 for its extremity 3a to reach towards 'the front of the loom. By this arrangement of'devices as' the crank shaft C revolves so will the cam 2, which is lixed thereon, re volve, and this 4revolving of the cam 2 will cause the lever 3 to rise and will allow it' by gravity to descend at the exact time that the picking or throwing of the shuttle necessitates to meet the requirements of the Checking actions of the swell lever 14 here- `ina"ft'er described.

By the'employment of the. cam 2 which is adjustably-iixed by pinchingscrews or otherwise upon the crank shaft C I am en-` of a cam Vabled to regulate or adjustsaid cam 2 in fixing in to be mounted upon the crank shaft C Within and lever arm 4 in order that this latter may oscillate loosely upon the sword in 5 to enable the extension or adjustable nger 7, secured to said lever 4, to come into con- 1by the slayboard A in well known manner.-

As vwill be observed the lever 4 may have the finger or attachment 'l' which is secured to2` it by screws 7a,so adjusted that said projecting member 7 will at all times be in Contact with thespring 8 that is xed to 'theback finger 9 above described.

The devices hereinbefore described are brought intooperation at the desired time by the adjustment ot the cam 2 upon the crankshaft 'C so that when the shuttle is entering the shuttle box the lever 3 will Qcom'menee yto rise and will gradually force vthe lever 4,;tlie extension 7 carried by said vlever L.hand the spring 8 to press more and more'upon the backlinger 9 to cause this latter ,to press upon the swell lever 14 to fcarr' voutthe checking or retarding actions grae ually as the shuttle is entering` the sshuttle box in known manner. By the several parts being made adjustable, the said actions ofthe devices may be regulated to take place at the desiredtime and', under conditions which will prevent wear and deterioration as is hereinbefore stated.

l lhestoprod or shaft 9b is of the well known type of stop rod used in looms and extends from mydevices which are mounted on one end ont the loom to similar devices lmounted. on .the opposite end of the loom so ythat the checking of the shuttle is carried out at both ends yof the loom by my devices being used'in said two positions.

f The cam 2 is shown by Figs. l,A 2 and 4 the end frames D in looms Where the: posiztion of. the crank is such as will permit said cam2 tobe fixed upon said shaft in said pon' ,55

sition, whereas in looms in which the crank shalty C is too close to the end frame D to permitsaid cam so to -be mounted then said cam 2 maybe mounted upon the outer ends of the crank shaft C as is shovvnby Fig. 3

inwbch case the supporting bracket for the lstud l0A (upon which the lever 3 is mounted) ,.will extend outwardly from the end frame 'D .to the lever 3 mounted upon it. In this case the lever arm 4 is mounted upon a short shafta which is supported by brackets. 5b

v stop an extension from the and 5c fixed to the slayboard A while the vertical fiat-spring 7 b is fixed upon the short shaft 5a in the position shown by Fig. 3 so that it may contact with the upper end of the back finger 9 which is fixed upon the ordinary stop rod 9b of the loom where the swell lever M is mounted upon the slayboard A in the usual manner.

y Provided the well known toothed wheel 10 and balance wheel 1l (shown by Fig. 3) which are carried by the crank shaft C are suciently far apart to permit the lever 3 to extend between them then the cam 2 may be mounted upon the crank shaft C between said two wheels.

A The arrangement of my devices as is hereinbefore described enables the employment of my cam. actuated Vdevices in connection with looms in which the crank shaft revolves in one direction to beat u the weit as well as in connection with o er looms wherein the crank shaft revolves in the opposite direction to beat up the'v weft since the actions of my cam are the same in both cases and its adjustment in position relative to the ,sweep with the cam, a second lever having a pro-Y ection engaging the lever cooperating with the cam, means for ivotally mounting the second lever on the slay board, a hat spring, means for securing said flat spring to the stop rod, and a second projection on the second lever adapted to contact with the flat 2.. evices for rchecking or arresting shuttles within the shuttle boxes of looms, the combination with the looin crank shaft, slay board, swell lever and lonvitudinal rod, of a eem mounted on the crank shaft and capable of adjustment, a pivoted lever cooperating vwith Vthe cam,y a second lever ivotelly mounted on the slay board and a. apted to engage the lever cooperating with the cam, a vertically projecting spring, stop rod in which the vertically projecting sprlng is adjustably fixed, a rejection engaging the spring and operate by the secon lever, a second spring extending horizontally from theA vertically proieeting spring to intervene between it and the proiection, and Ineens for securing the second s ring to actuate in coniunction with the swelv lever.
